Introducing Magnolia Black Tulip Tree
This is an absolutely gorgeous dark purple magnolia – the flowers are shaped like a tulip and are a deep purple colour. They also have a lovely scent. Magnolia Black Tulip can be a shrub or small tree, and it flowers at the beginning of spring.
The flowers are quite big at around 15 cm, and what’s lovely about this magnolia is that it usually blooms for a lengthy period of time. Sometimes you might be surprised by another round of flowering in the middle of summer.
Magnolia Black Tulip can be used to create a hedge, but is equally well planted in a large pot. This particular hybrid of magnolia comes from New Zealand and was made by combining the Magnolia ‘Vulcan’ with Magnolia 'iolanthe’.

Propagating Magnolia Black Tulip from Cuttings
You can propagate your own Magnolia Black Tulip, by taking a softwood cutting either during spring, or early in the summertime. The length of the cutting should be around 15 to 20 cm.
Once you’ve got your cutting, take off the leaves on the lower part and make a vertical cut of around 5cm in the stem. You can dip the cutting into some rooting hormone before planting it in perlite that’s been moistened.
Give the cuttings sufficient water and then cover them with a plastic bag to create a greenhouse effect. Put the pot or planting container in a warm place with indirect light, and then remove the bag about twice a week to give the cuttings some air.
They will need to have sufficient moisture until they have rooted properly and if you give them a regular misting, you should see roots within a few months.
Once the roots have established themselves, the Magnolia Black Tulip cuttings will need a hardening off period and can then be planted outdoors from the middle of autumn to the middle of spring.
Magnolia Black Tulip Propagation by Air Layering
Another way that you are able to propagate a Magnolia Black Tulip is a process called air layering. This involves cutting an existing branch and then packing a moist growing mixture around the cut so that roots are able to grow from it.
If you would like to give this method a try, the beginning of spring is a good time and do it with branches that are about a year old. You can make a cut parallel to each other in a circular pattern around the branch and space them just under 4 cm apart.
Join the lines by making another cut and take off the bark. Get hold of some sphagnum moss, wet it, and then wrap it around the cut you’ve created. You’ll probably need to secure it in place. You’re then going to put a layer of plastic wrap over the moss and tape it in place.
Be sure to keep the moss wet enough and when you eventually see roots sticking out of it, you can remove the cutting from the main plant.

Sunlight Needs
The black tulip magnolia can grow well in either full or part sun, giving you options for your garden needs.
Watering Schedule
Magnolia Black Tulip needs deep watering often, especially for the first couple of years. This helps it to create a healthy root system. Once the plant is established, you don’t need to water as often, but when you do, make sure it’s a good thorough watering session.
Soil
Your Magnolia Black Tulip needs a well-draining soil. It should have plenty of organic matter, have even moisture levels, and be acidic. The plant does not enjoy wet or heavy soil.
Pruning
The ideal time to prune your Magnolia Black Tulip is at the end of winter or end of summer. This helps the plant not to bleed sap. Pruning should be kept to a minimum and just enough to keep the desired shape of the shrub or tree.
Fertiliser
The Magnolia Black Tulip will need a general purpose fertiliser applied ahead of the spring when new growth begins.
Common Black Tulip Magnolia Problems
Scale
Scale is a well-known pest because it’s known to affect so many plants. These insects are sap sucking and take away from the nutrients that your plant needs to thrive.
If you are dealing with a light infestation, you can simply prune the branches that are affected and be sure to check your plant well for any pests that might be hiding out.
You can also use rubbing alcohol on a cotton bud and put it directly on the bugs to kill them off. A great preventative measure is to spray your plant with something like neem oil at the end of spring as the new leaves appear.
Coral spot
This is a fungal disease that results in the dieback of branches. Once the branch has died, you’ll see coral colour spots form on the surface. Try and prune only when the weather is dry and cut branches at the collar at the base of the branches.
The cut will heal more quickly here and minimise the chance of infection. If you do notice that die back is happening after you have pruned, get rid of any dead plant parts so that the infection doesn’t spread.
Any infections should be quickly pruned out so that spores can’t spread to other parts of the garden.
Honey fungus
This fungus got its name because of the honey colour mushrooms it produces. These usually show up at the end of summer or in autumn. The fungus spreads underground and then kills off the roots of plants.
Signs that you might be dealing with honey fungus are plant dieback, leaves that look pale, a lack of flowers, and bark that is cracking and seeping. It can be tricky to spot honey fungus because it spreads under the soil. It also doesn’t always produce mushrooms which are a giveaway sign.
There aren't any chemical treatments available to treat this fungus so you’ll have to get rid of the infected plant, roots and all. Be sure to inspect any neighbouring plants as well in case the fungus has managed to spread further.
There are a few things that can help minimise the spread of honey fungus and watering and pruning your Magnolia Black Tulip well is important. You can remove a soil layer around the base of the plant as anything planted very deeply is more at risk. You can also dig the soil to up roots and break any infected roots.
Phytophthora root rot
One of the common signs of Phytophthora root rot is that the older leaves turn purple and red. You might also notice that the bark is a darker colour. Stunted growth is another sign.
If you are looking for a treatment, you could use a 3% solution of household hydrogen peroxide to treat your soil. You use a mixture of 1 part peroxide to 3 parts water.
You should allow enough time for it to really get into the soil before you start watering again. Another useful fungicide is anything containing copper as this also helps to protect the plant from infection.
Magnolia Black Tulip Frequently Asked Questions
Source: Ecolife Plants
Why does my Magnolia Black Tulip keep dropping its leaves?
This is completely normal as magnolia leaves turn yellow and drop off when they are old. This usually happens in the springtime when flowering starts. In some years, the magnolia will drop off more leaves than others and don’t worry if it seems like a large quantity of the plant’s leaves.
What is the best fertiliser for a Magnolia Black Tulip?
We recommend a multi-purpose 10-10-10 fertiliser.
Is Epsom salt a good thing to feed to Magnolia Black Tulips?
Magnolias need their magnesium as much as they need enough water. Epsom salt is a great source of magnesium for your plant.
Why is my Magnolia Black Tulip not flowering?
The trick to getting a magnolia to bloom is to make sure that the soil pH is right. The Magnolia Black Tulip needs a pH between acid and neutral.
How long does a magnolia live for?
Some species of magnolia can live between 80 and 120 years. The oldest known tree that was ever recorded was 320 years old, and was found in Italy.
Is the root system of the Magnolia Black Tulip deep or more spread out?
The Magnolia Black Tulip has an extensive root system but it doesn’t grow very deep. The roots grow outwards instead of downwards, so they are quite close to the surface of the soil.
